Oh, in IBM history "Think" was much bigger than just notepads. "Think" was a command from venerated IBM founder Thomas J. Watson, and in the Olden Days IBM used to put that slogan on wall signs (see http://en.wikipedia.org/wiki/Think_%28IBM%29) that were hung EVERYWHERE.

Even in the restrooms: (http://www-03.ibm.com/ibm/history/ibm100/us/en/icons/think_c...)

In a restroom at IBM’s Watson Center, a supervisor had placed a sign above the sink. It had a single word on it—‘THINK!’ The next day, when he went to the restroom, right below the sign, immediately above the soap dispenser, someone had carefully lettered another sign that read— ‘THOAP!’

They also made desktoppers with the slogan for executives, and the story goes that you could tell how high up in the legendary IBM bureaucracy an IBMer was by how big and ornate his THINK sign was -- junior execs got tiny signs made of plastic, senior ones got big ones made of fancy woods and metals.
For the frugal traveller who wants to live in a van but move around (perhaps while developing your web app or similar), we've started a community where fellow RV'ers (or people who just like RVers) offer their driveways to others to camp on for a night or two for free - http://www.boondockerswelcome.com. We're going to start charging a small annual fee to cover our costs, but for $25/year you can travel all over the continent and park your van for free. Of course, this doesn't solve the bathroom or showering issue, as most people aren't opening up their bathrooms to their guests. But my mom (who has a small Roadtrek RV, which is really no bigger than a van and has no shower), has travelled for 5 months at a time getting by with showers in the occasional truck stop or an outdoor shower that she uses when they're parked in the forest. (There's also tons of free parking for RVs in US National forests BTW, plus lots of other spots. My mom writes e-books all about the free "boondocking" locations she's discovered complete with GPS co-ordinates and interesting nearby attractions - find them at http://www.frugal-rv-travel.com.)

What I would really like to see is a guesstimate of the volume of user behavior/analytics data that FB/Twitter generate. It would be interesting to see the average amount of data per user-interaction.
I've got javascript disabled, and for some reason the page needs javascript to display anything other than the header. I was initially confused as to whether this was a joke of some sort.
Facebook, at its core, is about private (hah!) networks of one's friends and families. It was always designed to be insular, to form self-selecting groups. It's a platform that's inward looking. The inability to create and publicize new content with it to the Net at large is a feature, not a bug.

Self-driving is obvious. The infrastructure will be in place to allow, if not require, highly automated traffic. Just get in the car and tell it where to go; leave navigation, congestion issues, etc. to the onboard computer linked to the city traffic network.

Which obviously leads to an otherwise not obvious major design factor: round. Once the norm is for the occupying humans to not have much, if any, control in driving, the paramount drivetrain issue will be how to move the vehicle in any suitable direction on very short notice. Replace the "front wheels turn a few degrees" paradigm with zero-turn-radius or any-direction movement, and the vehicle's ideal shape is a circle.

Seems obvious to me.

What's not obvious to me is how crowdsourcing will come up with such a model. To wit: how does crowdsourcing overcome non-ingrained memetic patterns?

ETA: BMW is partnering with crowdsourcing pros Local Motors of Phoenix to run the contest. Local Motors already has a crowdsourced, on-sale car to its credit, the Rally Fighter. Then the outcome of this contest will be amusing, as the Rally Fighter seems the utter opposite of the design pursued here.

Wowwwww !! These look absolutely beautiful. But one still needs to own a piece of land.

I'm going to guess it's similar to the experiments described here: http://en.wikipedia.org/wiki/Learned_helplessness
I drink (black) tea with milk. So here's a _very_ anecdotal/hypothetical thought: my brother switched to drinking black tea without milk. A couple of years later, he had a kidney stone; and the doctor claimed it was the tea.

Some of the tannins that give the tea its color are small enough to get into the blood stream, but get caught in the kidney, possibly leading to stones. So if you add milk, the big fat molecules of milk trap these, which prevents them from getting caught in the kidney; hence no stones.

I could be wrong...
This is one thing that has always made me skeptical about FBs survival.

The majority of it's use seems to be for very short term things, like friends sharing what they are currently doing.

There is little value in most FB posts that are years old. As opposed to wikipedia which is a gradually building blob of knowledge.

Let's say FB was down for a week, many people would use G+ instead for their social networking needs and how many would come back?
I don't see what's bad about Facebook. 99 percent of the content is gossip, siloed, tucked neatly in a corner of the Internet, covered with ads. Would you rather have any idiot's rants and raves about their boy/girlfriend all over you search engine results? Long live chit chat, but keep it where it belongs.

Incidentally, ill thought features like the timeline or apps like the Washington post that try to turn the site to a news site or a personal mausoleum will fail and be retracted few months later

"is class disdain because I'm too well off to consider it or class disdain because when I wasn't well off we had too much pride to ever stoop to anything like that."

Normally when you read stories about these outliers in life there is always a story behind it. I remember the case of the guy on the street corner who was discovered as having singing talent, made it to network news shows, was given some sort of leg up opportunity and then it turned out (iirc) that he was just some mentally ill guy and that's why he was living on street corners and homeless.

In a quote in the OP there is this as one related example:

"I didn’t waste time watching re-runs of Cheers for three hours on Netflix. I read a lot of books, I worked on my music more. When I lived in a house, I never really used my guitar because it was in another room. When I was in the RV, everything I owned was in the same room so I played my guitar a lot.”"

So we have someone who didn't play his guitar because it was in another room. And someone who spent 3 hours per day watching a sitcom on netflix. And you wonder why he is living in a van?

By the way, I located my personal laser printer in an outer office. That way each time I print something I have to getup to get the printout. I could easily put it next to my desk and only have to lift my hand. But I choose to do the extra work and get the nominal health benefits from getting off my ass as much as I can (which costs $0).
Yeah I hear you. It can be difficult to follow if you're unfamiliar with the landscape is all. Maybe start things off by watching how the CPU works. Both the CPU and PPU work via a Step() function that is the entry-point for their respective functionality.

Just to add my ketamine experience, I broke my arm a few years ago. I split both the bones in my left forearm clear in two. At the hospital they set it and gave me ketamine while realigning the bones and putting a cast on. It was a terrible experience. It felt like time was just going so slowly and everything was out of my control. Terrible.
I would have loved to save money right out of school, being as frugal as I am, but I was married when I graduated and the first thing my wife wanted after I got my first (low paying) full time job? A house.

So much for the life of a cheapskate.
While I agree manufacturer ADD is a problem, I reject the idea that every phone should come with two years of support. Those of us who buy high-end phones on-contract forget that off-contract Android phones can get very, very cheap. Sub $100 isn't hard to find and I've heard of devices as cheap as $50. If not providing updates is what helps make what would have been a $100 phone into an $80 one, I think that is a reasonable tradeoff for a manufacturer and their customers to make.

Today that no-updates line is being drawn in the wrong place and it really shouldn't apply to phones sold on-contract, but that doesn't mean the possibility should be banned entirely.
So basically OpenVZ is what gave VPS nodes a bad name when they came on the market.
It is interesting also to note that the ability to lead any kind of normal or predictable life in this fashion is itself a privilege. People in the software business can get away with wearing the same clothes, coming in wrinkled, missing the occasional shower, and, for that matter, getting in a little later after having to move the van in the middle of the night. Our field is extremely accommodating.

Put yourself in the shoes of a call-center worker (and if you want to be mean to the issue, make that call-center worker female). These jobs have dress codes. They're also aggressively monitored during the day and require attentiveness and a cordial demeanor. And obviously, a typical call-center worker cannot depend on the idea of taking off in the van for a month, driving to some other city, and having the same economic prospects when they arrive. Most people cannot afford to be playful with the idea of job security.

It's weird to find yourself thinking, "must be nice to be an iOS developer who can live in a van". Especially when you think of the people who do it because they're forced to do it.

I found the article to be a little glib about its subject. Glib is the word I would use, for romanticizing a scenario that many Americans actually experience as an intractable nightmare. I found myself first thinking about how nice it would be to pull up to the oceanfront, lay down in my "living room" van, and doze off reading a book while listening to the waves... then I thought of the scene in The Pursuit Of Happiness (not a great movie, but a great scene) where Will Smith has to put his kid to bed in a closet in a train station.
I think his point is that apple makes the safari homepage apple.com . They know that every mac they sell will start there. Despite knowing that, they don't seem to have thought that users might be annoyed by the video playing every time. I don't think that really matters, but it's interesting to talk about.
I totally agree with this,
Facebook solved purely a social problem and this makes them subject to being at an existential risk of no longer being socially relevant ("cool").

This will get much easier when robocars come out. You won't have to worry about police and zoning laws, the car can move every once in a while or continuously be moving. If robocar renting takes off you don't even the cash up front to pay for one. Showers and toilets can be separately moving robocars so this can all be done in small vehicles rather than large RV's. The fuel would electric (robocars recharge themselves from electric gas stations) so the costs of all this would be minimal as well. If this all plays out well, apartments, and even houses should see a drop in value (a good thing because too much of wealth is being plowed into the unproductive economy of land owning - it can instead shift to purchasing engineered products).
Of course, it isn't a given that you will be able to find a sufficiently large overlapping substring in the OS binary data.

It seems that it's a given that you will not find that substring. The larger it is, the less likely you will find it and the less likely it will repeat in the uncompressed file.

It is amusing how this title Facebook "the Devourer" reminds one of some dark Hindu deity, such as Kala [Time] the Devourer:

"At the dissolution of things, it is Kāla [Time] Who will devour all" (Mahanirvana-tantra, cited in David Kinsley, Tantric Visions of the Divine Feminine: The Ten Mahavidyas, p. 122.)

Better known is Krishna's theophanic revelation to Arjuna on the sacred plain of Kurukṣetra: "Behold, I am become death, the destroyer of worlds," which is also translated, "I am terrible time [Kalo, from "Kala"] the destroyer of all beings in all worlds" (Bhagavad-Gita, 11:32). Oppenheimer reportedly quoted this very line immediately after first nuclear detonation in history at Trinity Site, New Mexico in 1945.

Surely Facebook is too trivial to merit such cosmic appellations and apocalyptic titles as "the Devourer." Such language is best left to poets, seers, prophets, and mystics. In the context of discussing the technology industry, it is wildly hyperbolic.

The lesson is that you can't just ignore politics. You can't just leave politics to the politicians.

The same people who bitch about the government typically refuse to take control of the government. Democracy is bullshit and it's time for technical and scientific people to create a Platonic state.

The price good men pay for indifference to politics is having their businesses destroyed by evil men.

What mystifies me is how all of these smart technologists and scientists refuse to use their intelligence to take over the state.

People should have to pass science and math exams if they want to vote. It's that simple.

I remember it well. I drove up to Bluff Mountain tower (TN) with a couple of friends on a clear summer night. From up there it was a spectacular sight. It was much more beautiful than Hale-Bopp which I saw from Bear Mountain (NY). The only problem - and it was a big one - was that you couldn't really see Kohoutek unless you were up high where Hale-Bopp could be seen from light polluted suburbs.

Every industry has those people, though. With seven billion people in the world, there are going to be a lot of incredibly amazing people that we will never hear of, just because the bandwidth it would take to even hear their names (much less really understand their contributions) is just far too great.

Even though there are millions of outstanding contributors to our societies and technologies whose names I will never know, I am grateful for them.
Yeah, I don't know. You make a good point too. Maybe the parent comment was worded too stridently, but I thought it asked a valid question, and I think HN needs that question to be asked more, not less.

String reversal, and all the other common interview questions are simply a microcosm of what a developer does day to day. Programming is about comprehending abstractions and composing them into a greater whole that solves a specified business problem. Reversing a string is exercising those same mental faculties. There is literally no difference between working out the steps to reversing a string and working out the steps to pulling data from a database, transforming it, and displaying it on the screen, except that for the second example one can Google then copy/paste about 90% of it. Asking "reverse a string" type questions will weed out the Google-jockies (obviously there's nothing wrong with Googling for an answer, but if you have to Google for everything you're in the wrong line of work).

> Remember Facebook?

This delusion that Facebook is somehow dramatically more replaceable than Google or Amazon is kinda amusing. There are plenty of other places to buy online and plenty of other places to search. I can't imagine the mental contortions that are required to hold both of these beliefs at once: "Facebook is replaceable," and, "Google is irreplaceable." They are both replaceable, but it would be tough in both cases.
Funny but I think there is a growing field of studying 'ologies'! In bioinformatics, 'omics' is a subfield on its own
> "There are many assumptions in the article and in your comment. "

I'm confused. As I read the post, it contains the bits "The most important step comes next, where you try to find out what ketamine is actually doing, since, again, there's no happiness dial in the brain. ... This step is crucial, because it allows you to find out which effect of ketamine is providing the benefit, because there are many."

While the possibility you take as 'assumed' is the jumping off point for the hypothesis, it is explicitly a testable hypothesis for which the necessary test to (in)validate the original assumption is explicitly defined.

So what exactly is the problem?
Call me crazy, but I love it when a person or machine admits "I don't know" -- doubly so if they distinguish between "it's not possible to know" and "we simply haven't handled that case yet". That can be extremely useful information to have!

The True Internet Explorer 9 Commercial
Exactly, I consider Mike to be acting in bad faith here. Mike was willing to accept $100 (which in most of the world constitutes many hours of labor) not just once, but every time people wanted to play again. He was willing to accept real money for something that he believed was literally impossible. Mike didn't hint at the impossibility in any way. E.g. if he had said "Have you read the FAQ and you still sure you want to play?" I would view it in different light. But no, Mike seemed all to eager to accept the money.

So yes, then when a taker appears he's either not very bright (and therefore you shouldn't take advantage of him) or he's trying to out-hussle (and playing legalese with the terms is then fair game). After Mike got beaten at his own game he then continued to (a) weasel out of it (b) threaten legal action (c) attempt to deflect.

Not exactly a class act by Mike.
Absolutely. From what I understand, one of the big reasons ICS updates have been so much more difficult than Gingerbread ones is that the driver interfaces changed for a lot more things in that jump (exacerbated by the tablet-only Honeycomb in between).

That aside, I really like, and adhere, to the sleeping tip. In college (taking design and development) there were always kids who would pull all-nighter and then sleep during class. I never really understood the point.

Just go to bed at a decent time and if necessary, wake up earlier.
